But notice that (equal (string-as-multibyte (unibyte-string #x68 #xc3 #xa9 #x6c #x6c #x6f)) "héllo") => t And notice (equal (unibyte-string #x68 #xe9 #x6c #x6c #x6f) "h\351llo") => t whereas (equal "h\351llo" "héllo") => nil while (equal "h\u00e9llo" "héllo") => t It should probably be called an error that the print form of "h\351llo" is "héllo" on an utf-8 terminal. That does not particularly help to make things less confusing since the input forms are non-equivalent. -- David Kastrup
